Esther 3:12-13

12Then the king’s scribes (secretaries) were summoned on the thirteenth day of the first month, and it was written just as Haman commanded to the king’s satraps (chief rulers), and to the governors who were over each province and to the officials of each people, each province according to its script (writing), each people according to their own language; being written in the name of King Ahasuerus and sealed with the king’s signet ring.

13Letters were sent by couriers to all the king’s provinces to destroy, to kill and to annihilate all the Jews, both young and old, women and children, in one day, the thirteenth [day] of the twelfth month, which is the month of Adar (March 7, 473 b.c.), and to seize their belongings as plunder.
